摘　　要：针对高速公路沥青路面的热拌沥青混合料的离析问题,对道路的各项路用性能产生了不利影响的现状,结合云湛高速公路工程建设中对沥青混合料离析的试验研究,对热拌沥青混合料的不同种类的离析对沥青路面路用性能的影响进行了探究。鉴于混合料的离析与否是沥青路面使用性能和使用寿命关键的控制因素之一,并在对室内马歇尔试件研究的基础上,总结了级配离析、温度离析等离析的相关影响,并提出一定的控制指标。In view of the segregation problem of hot mix asphalt mixture of expressway,which has a negative impact on the road performance,combined with the experimental research on the segregation of asphalt mixture in the construction of yunzhan expressway,this paper probes into the influence of the segregation of different types of hot mix asphalt mixture on the road performance of asphalt pavement.In view of the segregation or not of the mixture is one of the key control factors of asphalt pavement service performance and service life.Based on the research of Marshall laboratory test-pieces,this paper summarizes the relevant effects of segregation,such as gradation segregation,temperature segregation,and puts forward some control indexes.
